Detailed explanation-1: -Your trachea divides into your left and right bronchi. The bronchi carry air into your lungs. At the end of the bronchi, the bronchioles carry air to small sacs in your lungs called alveoli. The alveoli perform your body’s gas exchange.

Detailed explanation-2: -The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung.

Detailed explanation-3: -In the mediastinum, at the level of the fifth thoracic vertebra, the trachea divides into the right and left primary bronchi.

Detailed explanation-4: -After the tertiary segmental bronchi, the airways continue to fan out into bronchioles. Bronchioles then divide into three types: conducting, terminal, and respiratory. There are 20-25 branching generations of conducting bronchioles after the tertiary segmental bronchi.

Detailed explanation-5: -The trachea is the long tube that connects your larynx (voice box) to your bronchi. Your bronchi send air to your lungs. Your trachea is a key part of your respiratory system. The trachea is made of rings of cartilage.
